Oil dripping from a car can tarnish your driveway or garage floor, but it's easy to clean up with some cola.

All you have to do is pour a few cans of room-temperature cola on the stain, and let it sit overnight. In the morning, blot it with some old towels, and rinse off any remains. If there's anything left over, you could try using dish soap, or any of the other methods included in the source link.
